hi unicorn. a friend of mine puts the duvet tucked in under her ds and a cellular blanket on top. apparently having the duvet underneath traps all of his body heat and he remains cosy all night...don't know if this will help but worth a try?

ooh thanks sophable.. that sounds like a good idea...
I bet he will find a way to get on top of the blanket though; it seems like he moves around a lot in his sleep, then wakes himself up as a result iyswim!

unicorn, tbh, if he's in a 2.5 tog grow bag, and maybe longsleeved vest/pj's underneath, he should be alright without blanket...could it be that he is waking cuase he is getting in a kerfuddle with his bedding rather than cause he is cold. i would be inclined to up what he wears under the grobag and not have a blanket at all...

thanks morningp..
his room has 2 outside walls so does get quite nippy once the heating is off.
He has a bed rail, and I don't think there are any vents anywhere.

I have just had another thought, because he turns himself totally upside down, it may be that he prefers to sleep closer to the door, where he can see a light (bathroom).Or it may be that he just prefers sleeping in that position,(and I keep turning him back!!!!!!!!) so maybe I need to try a nightlight, and/or, turn the bed around?

The grobag is supposed to be used INSTEAD of a duvet, blankets etc, according to them. I certainly never used them together. My ds who is three now wears PJs and has a 4.5 tog duvet which we tuck in VERY firmly before he goes to sleep and it stays in place. I don't think he's a very restless sleeper though. A duvet AND grobag seems a big much to me.
